My observations are all experience based and not scientific but I suspect the lack of a front hood to shield the inside of the optic from glare make the tube style micro red dot optics very vulnerable to incoming glare. This is not meant to be a hate article. To the contrary, the micro red dot is still the most common red dot optic I own but there are people who feel there are no disadvantages and I would disagree. For those who shoot outside, or in the field, or downrange, shooting into the sun is an unfortunate reality. In our shooting we have had to actually put a hand over micro red dots to cut the glare. We have not seen this problem to the same extent with longer tubular designs such as the Aimpoint CompM4 or Trijcon Ta45/44 ACOG scope (not the short models).
If your shooting requires you to regularly function in high glare scenarios I would highly recommend you do not use a micro red dot tubular style unless you're willing to deal with more glare.
